I'm having an issue with a bridge collision. The matId is #85, metal. Some of my tanks, and wheeled vehicles, can cross it with no problem. Some other tanks, though, bounce up and down (like an aircraft does on a carrier when you spawn it too far into the flight deck...collision clipping). All my tanks and wheeled vehicles have the same #37 matId for the wheel collision.

The bouncing tanks go over other objects with #85 matId just fine, with no bounce. Just not this one bridge...

I've looked at some of the tanks that bounce, to make sure their col01 and col02 weren't too close to the ground (ground clearance), but this doesn't seem to be the case. I'm at a loss right now as to what could be the issue.
